Answer:
Step-by-step explanation:
Let x is the length of the square side.
We know: the two figures have the same area
<=>
= π
(r being radius)
<=> x =
r
perimeter square = 4x = 4*r*
perimeter circle = 2*r*π
<=> 390 = 4*r*
+ 2*r*π
<=> r = 29.16
=> perimeter square = 4*29.16*π
=> perimeter circle = 58.32π
Use vertical pipes around the value.
Example:
abs(-4) = |-4| = 4
Answer:
29/40
Step-by-step explanation:
Step-by-step explanation:
Y=-4x+3
2x+3y=19
2x+3(-4x+3)=19
2x-12x+9=19
-10x=10
X=-1
y=-4*(-1)+3=4+3=7
x=-1 y=7
